CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a divisional application of U.S. application Ser.No. 15/692,416, filed Aug. 31, 2017, the entire disclosure of which isincorporated herein by reference.

FIELD OF THE INVENTION

The invention provides a set of disposable medical devices, includingvarious intubating devices, which are combined with a disposable cameraproviding continuous visualization during and after placement in apatient. A sound device, such as a microphone, may be incorporated inmany devices and provides continuous monitoring of breath and heartsounds in a patient. The continuous visualization and sound monitoringof the patient are in real time and enable remote monitoring as well.Methods for rapid and accurate placement of a medical device in apatient are provided as well.

BACKGROUND

Various devices are available to stabilize a patient and facilitate hisbreathing, feeding and medication delivery. Such devices are used inpatients during surgical procedures, after certain traumas includingspinal cord injuries, and in patients suffering from certain medicalconditions including advanced Alzheimer disease. These devices includeendotracheal tubes, airway devices, feeding tubes, oral airways, nasalcannulas and the like.

The process of placing a breathing tube in a patient is calledintubation. Devices such as laryngoscopes, videolaryngoscopes,fiberoptic scopes, as well as other proprietary videoscopes have beendeveloped. These devices provide accuracy for initial placement, but donot provide continuous visualization or mobility of the image after amedical device has been placed in a patient. Newer devices, such asVivasight SL or DL endotracheal tubes, provide continuous visualization,but are costly because they depend on a single use of disposable camerasand they are not transferrable from one medical device to another. TheTotaltrack VLM supraglottic airway has a proprietary reusable camera foronly its one device, and it cannot be transferred to other medicaldevices.

Thus, there remains the need for improved devices which can be easilymonitored remotely by a qualified personal during placement and afterplacement for an adverse reaction. After a medical device has beenplaced in a patient, the need remains to monitor in real time thepatient's possible adverse reactions such as for example, aspiration,airway secretion, apnea, etc.

Certain medical devices which provide continuous visualization aredescribed in U.S. Pat. No. 9,415,179, and Patent Publications US2016-0038008; US 2016-0038014; and US 2016-0262603. In these devices, acamera is placed inside of a camera tube which is a separate lumensealed at the distal end. This prevents the camera from coming into acontact with a patient's body and allows for the camera to be reused invarious devices and between different patients without the need forsterilization. While these devices may comprise a disposable camera, thedevices still comprise a separate camera tube sealed at the distal end.

DETAILED DESCRIPTION

The present invention provides medical devices equipped with a camerafor intubation, ventilation, feeding and monitoring of a patient. Thepresent invention also provides methods for rapid and accurate placementof a medical device in a patient and remote continuous real-timemonitoring of the patient after the placement.

The invention provides a set of medical devices equipped with adisposable camera which can be transferred between the devices asneeded. These devices provide continuous visualization of any of thefollowing in a patient in real time: nasopharynx, pharynx/hypo pharynx,supraglottic structures, airway, internal organ anatomy, vocal cordsduring normal and abnormal ventilation. The devices also allow detectionof abnormal anatomy and abnormal vocal cord movements.

A camera in the present devices comprises a digital camera coupled to apower cord. The digital camera may comprise CCD (charge-coupled device)and/or CMOS (complementary metal-oxide semiconductor) sensors. Thecaptured images may be transmitted either with a wire or wirelessly.

Referring to FIG. 1A, this embodiment provides an endotracheal device,generally 10. The endotracheal device 10 comprises an endotracheal tube12 with a distal end 12A and a proximal end 12B. The endotracheal tube12 comprises an inflatable cuff 13 wrapped around the endotracheal tube12 proximally to the distal end 12A. The cuff 13 can be inflated withmeans 14 after the endotracheal tube 12 is placed in a patient. Theendotracheal tube 12 comprises a plate 15 positioned near the proximalend 12B. The plate 15 is perpendicular to the endotracheal tube 12 andprevents the endotracheal tube 12 from sliding into the patient's bodyafter the device 10 has been placed into the patient.

A camera 16 is sealed externally along the proximal-distal (12B-12A)axis of the endotracheal tube 12. A diameter of the camera 16 is notlimited by a diameter of the endotracheal tube 12. The diameter of thecamera 16 can be larger or smaller than the diameter of the endotrachealtube 12. This may be particularly beneficial for pediatric patients andpatients with abnormal anatomy.

In the embodiment of FIG. 1A, the camera 16 is positioned proximally tothe cuff 13. The camera 16 may comprise a battery (not shown), and/orelectric wire 18 for connection to an external device such as a computerand monitor (not shown). The camera 16 may also comprise means fortransmitting images wirelessly. The camera 16 may further comprise alight source which can be built-in the camera 16.

At least in some applications, the camera 16 is a digital cameraequipped with a chip and the camera 16 collects and transmits imagescontinuously. The camera 16 can be connected wirelessly or hard-wiredwith a computer network (not shown) which collects and analyzes imagesobtained by the camera 16. This arrangement permits for remote,continuous and real-time monitoring of the endotracheal device 10 duringplacement and after-placement in a patient. Thus, an accurate and rapidplacement of the endotracheal device 10 can be achieved. Further andbecause the camera 16 continues to acquire images after the endotrachealdevice 10 is placed inside of a patient, the patient can be monitored inreal time for adverse reactions such as bleeding, airway obstruction,shifting or malfunctioning, etc. of the endotracheal device 10 and otherreactions. The endotracheal device 10 may continue to transmit imagesand information for as long as it remains in a patient.

The endotracheal device 10 can be further equipped with asound-monitoring device (not shown) such as microphone which can monitorheart beats and breathing tones and can be connected by wire orwirelessly to a remote device which collects and monitors patient'svital signals.

In the embodiment of FIG. 1A, the camera 16 is placed proximally to thecuff 13 and externally to the endotracheal tube 12. It will beunderstood that the endotracheal device 10 can be built with anyendotracheal tube 12, including single-lumen and double-lumen tubes. Theendotracheal device 10 can be used for either pediatric or adultpatients. The endotracheal device 10 can be made in various sizes.

FIG. 1B is another embodiment of an endotracheal device 20 whichcomprises the endotracheal tube 12 with the cuff 13 and other elementsas described in connection with FIG. 1A. In the embodiment of FIG. 1B,the camera 16 is sealed externally to the endotracheal tube 12 along thedistal-proximal axis 12A-12B. Unlike the embodiment of FIG. 1A, thecamera 16 in the embodiment of FIG. 1B is placed under the cuff 13 andit collects images distally from the cuff 13. It will be understood thatthe endotracheal device 20 can be built with any endotracheal tube 12,including single-lumen and double-lumen tubes. The endotracheal device20 can be used for either pediatric or adult patients. The endotrachealdevice 20 can be made in various sizes.

It will be readily appreciated by a person of skill, that in theembodiments of FIGS. 1A and 1B, the camera 16 is sealed along theendotracheal tube 12. In other embodiments, the camera 16 can becombined with the endotracheal tube 12 such that the camera 16 can slideup and down along the proximal-distal axis 12B-12A of the endotrachealtube 12.

The camera 16 can be combined with the endotracheal tube 12 by beingsealed with an adhesive to the endotracheal tube 12. In alternative, thecamera 16 can be attached to the endotracheal tube 12 such that thecamera 16 can be separated from the endotracheal tube 12 and transferredto another medical device. This reversible attachment can be achieved byclipping the camera 16 to the endotracheal tube 12 with at least oneclip or by tying the camera 16 to the camera tube 12 with a rope, threador and/or by plastic and/or robber band. In alternative, the camera 16can be equipped with at least one ring which can slide over theendotracheal tube 12 and thereby combine the camera 16 with theendotracheal tube 12 such that the camera 16 can slide along theendotracheal tube 12.

FIGS. 2A and 2B provide another embodiment for an endotracheal tube 30equipped with a sleeve 32. In this embodiment, an endotracheal tube 12comprises a distal end 12A and a proximal end 12B. The sleeve 32 isplaced near the proximal end 12B. An inflatable cuff 13 is wrappedaround the endotracheal tube 12 near the distal end 12A. The cuff 13 canbe inflated with means 14. A camera 16 is combined with the endotrachealtube 12 by being placed through the sleeve 32, along the endotrachealtube 12 and under the cuff 13. The camera 16 can slide along theproximal-distal axis 12B-12A such that the camera 16 can be positionedright at the distal end 12A of the endotracheal tube 12, as shown inFIG. 2A. The camera 16 can also slide further distally under the cuff 13such that the camera 16 is now positioned distally to the distal end 12Aof the endotracheal tube 12 and provides images distally to the distalend 12A of the endotracheal tube 12, as shown in FIG. 2B. The sleeve 32is made of a flexible material, such as for example plastic or rubber.This allows for sleeve 32 to easily collapse as needed when the camera16 moves distally along the endotracheal tube 12. Compare the sleeve 32in FIG. 2B where the sleeve 32 in the collapsed position versus thesleeve 32 in FIG. 32A where the sleeve 32 is in a fully extendedposition.

At any time, a practitioner can manipulate the positioning of the camera16 through the sleeve 32, including to move the camera 16 proximally ordistally, and/or to remove the camera 16 from the patient while theendotracheal tube 12 still remains in place in the patient. Thisarrangement allows for transferring the camera 16 between differentdevices. This arrangement also allows for adjusting the position of thecamera 16 in the patient, depending on an area that needs to bemonitored. It will be appreciated that the device 30 can comprise morethan one camera. In these further embodiments, a second camera canprovide additional images from a location proximal or distal to thecamera 16.

A particularly important advantage can be obtained by combining thecamera 16 with a bougie, flexible stylet or any other tool which can beused for guiding the placement of the endotracheal tube 12 undercontinuous visualization from the camera 16.

FIG. 3A provides a further embodiment of an endotracheal device 40 whichcomprises an endotracheal tube 12 with a distal end 12A and a proximalend 12B and a plate 15 near the proximal end 12B.

The endotracheal tube 12 comprises an inflatable cuff 13 wrapped aroundthe endotracheal tube 12 proximally to the distal end 12A. The cuff 13can be inflated with means 14 after the endotracheal tube 12 is placedin a patient. The endotracheal device 40 comprises a camera 16 withelectric wire 18. In some embodiments, the camera 16 can be wireless.

In the embodiment of FIG. 3A, the camera 16 is attached to theendotracheal tube 12 externally with rings 44 and 42 which wrap aroundthe endotracheal tube 12. The endotracheal tube 12 is combined with thecamera 16 by placing the endotracheal tube 12 through the rings 42 and44. It will be appreciated that the positioning of the camera 16 alongthe distal-proximal axis (12A-12B) of the endotracheal tube 12 can beeasily adjusted by adjusting the positioning of the rings 42 and 44.

The camera 16 comprises two rings 42 and 44 as shown in more detail inFIG. 3B depicting rings 42 and 44 attached to the disposable camera 16.The number of rings can vary between different embodiments. In variousembodiments, from one to ten rings can be attached to the camera 16. Insome embodiments, rings can have an adjustable diameter. This can beachieved by equipping a ring with a clasp.

At least in some embodiments, a ring 46 has a clasp 48 as shown in FIG.3C which is a cross-sectional view of the camera 16 to which the ring 46is attached. The clasp 48 permits secure connection of the camera 16 totubal devices of various diameters because the diameter of the ring 46can be adjusted as needed. Thus, the same camera 16 with the ring 46 canbe used on a pediatric endotracheal tube and an endotracheal tube of theadult size. It will be appreciated that the camera 16 with the ring 46can be combined not only with an endotracheal tube, but with any othermedical tubal device. For example, the camera 16 can be combined with anendotracheal tube, oral airway and any other devices described in thisdisclosure.

In other embodiments, the camera 16 communicates with amonitoring device wirelessly. In some embodiments, the camera 16comprises a light source.

Referring to FIG. 6A, this embodiment provides a suction catheter with acamera, generally 80. The suction catheter 80 comprises a hollow tubalbody 82 which is not flexible in the embodiment of FIG. 6A. In otherembodiments, a suction catheter can be any suction catheter known in theart. A camera 16 is positioned inside the suction catheter body 82through an opening 83 which is in near proximity with a proximal end 82Bof the suction catheter 82. The camera 16 may comprise wire 18. Thedistal end 16A of the camera 16 is aligned with the distal end 82A ofthe suction catheter 82, while the proximal end 16B of the camera 16protrudes outside the patient's body such that the camera 16 can bepulled out from the patient while the catheter body 82 still remains inthe patient.

Another embodiment of a suction catheter 86 is shown in FIG. 6B. In thisembodiment, the camera 16 is placed externally along the suction tube82. The camera 16 can be glued or otherwise attached to the body 82along the proximal-distal axis (82B-82A). The distal end 16A of thecamera 16 is distal to the distal end 82A of the suction catheter body82. The proximal end 16B of the camera 16 is near the proximal end 82Bof the suction catheter body 82. The device 86 can work with suctioncaps.

Further embodiments provide a tubeless intubating device shown in FIGS.7A-7D, generally 90. The tubeless intubating device 90 comprises anellipsoid body 92 which has an upper oval surface 93 with a lumenopening 93A on the upper oval surface 93 of the ellipsoid body 92 asshown in FIG. 7A. The upper oval surface 93 is connected to the bottomhalf-ellipsoid surface 94 as shown in FIG. 7A such that the distal end92A of the ellipsoid body 92 is tapered because the bottomhalf-ellipsoid surface 94 is tapered at the distal end 92A. Theellipsoid body 92 encloses a lumen 96 which opens onto the upper ovalsurface 93 with the lumen opening 93A. The lumen 96 opens on theproximal side of the bottom half-ellipsoid surface 94 with a canal 98which connects to the bottom half-ellipsoid surface 94 and extendsbeneath the bottom half-ellipsoid surface 94. The bottom half-ellipsoidsurface 94 also connects to a handle 100.

The handle 100 comprises three parts connected together: the proximalpart 100A, the middle part 100B and the distal part 100C. The proximalpart 100A may be made in flat rectangle shape with a ring-holder 102attached on the bottom surface of the proximal part 100A. The 100A partbends down at about a 90-degree angle at its distal part where itconnects to the middle part 100B. The middle part 100B is also of flatrectangle shape and may vary in length. As can be seen from FIG. 7A, thecanal 98 is connected to the bottom surface of the middle part 100B atthe distal portion of the middle part 100B. The middle part 100Bconnects to the distal part 100C at its distal end. The middle part 100Bbends up at about a 90-degree angle at the distal part and connects tothe distal part 100C. The distal part 100C connects by its distal end tothe oval upper surface 93 of the ellipsoid body 92.

A camera tube 16 is attached along the handle 100 on its upper surfacesuch that the camera 16 extends along the handle 100 from its proximalend 100A and all the way into the distal portion 100C. The camera 16 canslide along the proximal-distal axis of the handle 100. The camera 16may further comprise a light source. In some embodiments, the ellipsoidbody 92 can comprise an inflatable cuff (not shown in FIG. 7A) which canbe inflated with a means 104.

In some embodiments, the handle 100 can be made of flexible material. Inother embodiments, the tubeless intubating device 90 can be designedwithout the cuff. In some embodiments, the camera 16 is fixed to thehandle 100. In other embodiments, the camera 16 can slide along theproximal-distal axis of the handle 100. The distal end 16A of the camera16 is aligned inside the lumen 96 and can capture images at thislocation.

The tubeless intubating device 90 can be used for intubating a patientwith an endotracheal tube of any size under continuous visualization ofthe camera 16. The tubeless intubating device 90 can be also used forextubation and for reintubation of a patient. It can also act as asupraglottic device with an endotracheal tube inflated with the cuff.

As shown in FIG. 7B, an endotracheal tube 106 can be loaded onto thetubeless intubating device 90 such that the proximal end 106B of theendotracheal tube 106 is secured on the tubeless intubating device 90with the ring holder 102. It will be appreciated that any endotrachealtube can be loaded into the device 90 and inserted into a patient.

As can be seen in FIG. 7B, the endotracheal tube 106 in this embodimentis equipped with a cuff 108 in the proximity to the distal end 106A ofthe endotracheal tube 106. The distal end 106A of the endotracheal tube106 is then passed through the canal 98 and through the lumen 96 suchthat the distal end 106A of the endotracheal tube 106 protrudes from thelumen opening 93A on the upper oval surface 93 of the ellipsoid body 92,as shown in FIG. 7B. The endotracheal tube 106 can slide along theproximal-dorsal axis of the tubeless intubating device 90 such that alonger or shorter portion of the endotracheal tube 106 protrudes fromthe lumen opening 93A. The endotracheal tube cuff 108 can be inflatedafter it is loaded into the device 90 and secured in place with the ringholder 102.

As can be further appreciated from FIG. 7B, after the tubelessintubating device 90 delivers and assists in placing the endotrachealtube 106 in the patient under direct and continuous visualization, thetubeless intubating device 90 can be easily removed from the patientwhile the endotracheal tube 106 remains safely in place under continuousvision. Thus, the tubeless device 90 can be used with a standardendotracheal tube to intubate and extubate a patient. The device 90 canbe also used as a supraglottic device.

As shown in FIGS. 7C and 7D, the tubeless intubating device 90 can beused for intubation and extubation of a patient with a supraglotticairway, generally 110. The device 90 can also be used for placement of alaryngeal mask airway. As shown in FIG. 7D, the supraglottic airway 110is secured in the device 90 with the ring holder 102 such that thedistal end of the device 110 is aligned with the distal end of thedevice 90 and the lumen 96 of the device 90 is aligned with the lumen112 of the device 110 and secured. Because the assembly of the devices90 and 110 is equipped with the camera 16, it provides continuousvisualization of patient's supraglottic structure during placement.

FIG. 8 provides a further embodiment for an endotracheal device,generally 120. The device 120 comprises an endotracheal tube 12 combinedwith a tool tube 122. The tool tube 122 is combined with theendotracheal tube 12 externally and is held in place on the endotrachealtube 12 with rings 124. The rings 124 are attached to the tool tube 122.The rings 124 can slide long the endotracheal tube 12 and move the tooltube 122 on the endotracheal tube 12 closer or further away from a cuff13 located in near proximity to the distal end 12A of the endotrachealtube 12. The tool tube 122 is hollow and a medical tool and/or camera 16can be placed inside the tool tube 122 through its proximal end 122B.The camera 16 can slide inside the tool tube 122 and may protrudedistally from the distal end 122A of the tool tube 122. The camera 16can be removed from the tool tube 122 while the tool tube 122 is stillin place in the patient. A tool, including but not limited to, biopsyforceps 124, esophageal stethoscope 126, cuff tube 128, suction tube130, nasogastric tube 132, stylet 134 and/or bougie 136 can be insertedin the tool tube 122 through an opening at the proximal end 122B.

Each of the ring holders 124 is attached to the tool tube 122. The ringholder 124 can be a complete ring or a half-ring. It can be alsoequipped with a clasp. It is understood that the tool tube 122 can beattached with the ring holder 124 to any tubal medical device. The tooltube 122 can then slide on the tubal medical device or endotracheal tube12 proximally or distally. The tool tube 122 can also rotate about thetubal medical device or endotracheal tube 12. In other embodiments, thetool tube 122 can be placed internally into an endotracheal tube orsupraglottic airway lumen. It will be appreciated that in the FIG. 8,the tool tube 122 is equipped with two rings 124 attached to the tooltube 122. In further embodiments, the tool tube 122 can be equipped withonly one ring or at least 3 rings. The positioning of the rings 124 onthe tool tube 122 can vary. It will be further appreciated from FIG. 8,that the positioning of the tool tube 122 along the body of theendotracheal tube 124 can be adjusted such that the tool tube 122 canbrought in near proximity with the cuff 13. A tool, such as the bougie136 can protrude distally from the tool tube 122, including protrudingdistally from the distal end 12A of the endotracheal tube 12. The bougie136 can then guide an insertion of the endotracheal tube 12 or any othertubal medical device to which the tool tube 122 is attached in thepatient's body.

FIG. 9A provides another embodiment for an endotracheal device,generally 140. In this embodiment, an endotracheal tube 12 is combinedwith a camera 16 which is attached to a hollow tool tube 142 externally.The tool tube 142 has a distal end 142A and a proximal end 142B. Thedistal end 16A of the camera 16 is aligned with the distal end 142A ofthe tool tube 142. The proximal end 16B of the camera 16 is aligned withthe proximal end 142B of the tool tube 142. As can be seen from theembodiment in FIG. 9A, the distal end 142A of the tool tube 142protrudes distally from the distal end 16A of the camera 16. When atool, such as any of the tools described in connection with FIG. 8, isplaced inside the tool tube 142, the tool can protrude from the distalend 142A of the tool tube 142. The tool, such as for example bougie, canthen be manipulated under continuous visualization by camera 16.

The endotracheal tube 12 is equipped with a cuff 13 and means 14 forinflating the cuff 13, as was discussed in detail in connection withFIG. 1A. The tool tube 142 is hollow and has an opening at the distalend 142A and an opening at the proximal end 142B. The tool tube 142 canbe capped with a cap 144 at the proximal end 142B, if needed. The distalend 16A of the camera 16 is aligned right above the distal end 142A ofthe tool tube 142. The tool tube 142 is combined with the endotrachealtube 12 by being inserted under the cuff 13. Accordingly, the distal end142A of the tool tube 142 can be distal to the cuff 13. This allows toinsert tools and conduct needed procedures distally to the cuff 13 underthe continuous visualization from the camera 16.

The tool tube 142 together with the camera 16 can slide along theproximal-distal (12B-12A) axis of the endotracheal tube 12. The tooltube 142 together with the attached camera 16 can be removed from thepatient while the endotracheal tube 12 remains inserted.

FIG. 9B depicts various tools, including, but not limited to, biopsyforceps 124 or the suction tube 130, that can be inserted into the tooltube 142. The tool tube 142 can be also used for insertion a bougie (notshown). A bougie either alone or in combination with any other tools canbe inserted into the tool tube 142. The bougie can be positioneddistally to the distal end 12A of the endotracheal tube 12. The bougiecan be then used for guiding placement in a patient of the endotrachealtube 12 under the continuous visualization of the camera 16.

When the tool tube 142 is not in use, the proximal opening of the tooltube 142 can be closed with the cap 144. This allows to establish aclosed system for ventilation through the endotracheal tube 12 while thetool tube 142 still inserted in the patient.

FIGS. 10A-10F are further embodiments of an oral airway device,generally 150. As shown in FIG. 10A, the device 150 comprises a hollowtubal body 152 with a lumen 154 into which the endotracheal tube 12 orany other medical device can be inserted.

The tubal body 152 has a proximal end 152B and a distal end 152A. Thetubal body 152 ends with a plate 156 at the proximal end 152B. The plate156 is perpendicular to the tubal body 152 and keeps the device 150 inplace from sliding into the patient's body. The tubal body 152 isslightly curved to follow the curvature of the patient's tongue. In theembodiment of FIG. 10A, a camera 16 is combined with the tubal body 152by being inserted through a channel 158. The channel 158 opens on theproximal side of the plate 156 and then goes through an opening 160 inthe plate 156. The channel 158 then continues through the wall of thetubal body 152 and opens inside the lumen 154. The camera 16 is insertedthrough the channel 158 into the lumen 154. In other embodiments, theopening 160 does not connect to a channel, instead the camera isinserted directly through the opening 160 and then through an opening inthe wall of the tubal body 152 in the lumen 154.

The camera 16 is inserted into the tubal body 152 through the channel158 or in other embodiments, the camera 16 is inserted directly throughthe wall of the tubal body 152 without the channel. The distal end 16Aof camera 16 can be aligned with the distal end 152A of the tubal body152. The camera 16 can slide up and down along the tubal body 152. Thecamera 16 can be removed from the tubal body 152, while the tubal body152 remains inserted in the patient.

In the embodiment of FIG. 10A, the camera 16 is equipped with a wire 18.In other embodiments, the camera 16 can be wireless. The opening 154 ofthe tubal body 152 can be closed with a ventilation cap 160 at theproximal end 152B. This allows ventilation while the camera 16 is inplace and continued visualization and monitoring of the patient.

As shown in FIGS. 10B and 10C, the oral airway device 150 can be usedfor inserting an endotracheal tube 10 into a patient. In the embodimentof FIG. 10B, the channel 158 enters the tubal body 152 through theopening 160 as was discussed in connection with the embodiment of FIG.10A. In the embodiment of FIG. 10C, the channel 158 enters the tubalbody 152 distally to the plate 156. Thus, the plate 156 in theembodiment of FIG. 10C does not comprise an opening for the channel 158.

FIG. 10D is a further embodiment of an oral airway device, generally170. The device 170 comprises a hollow curved tubal body 172. The curveof the tubal body 172 matches the curve of a patient's tongue for secureplacement. The tubal body 172 has a distal end 172A and a proximal end172B. The tubal body 172 ends with a plate 174 at the proximal end 172B.The plate 174 is perpendicular to the tubal body 172. The tubal body 172is hollow and it comprises a central lumen 176 through which theendotracheal tube 10 or any other device can be inserted into a patient.A camera 16 is inserted through an opening 178 in the plate 174 and isaligned along the proximal-distal axis (172B-172A) of the tubal body 172such that the distal end 16A of the camera 16 can be aligned with thedistal end 172A of the tubal body 172. The camera 16 can comprise wire18 or the camera 16 can be wireless.

The device 170 further comprises a second hollow tubal body 180 which isaligned with the tubal body 172. A balloon 182 wraps around the tubalbody 172 and the tubal body 180 in a near proximity to the distal end172A. Thus, the two tubal bodies, 172 and 180, are held together by theballoon 182. The distal end 16A of the camera 16 is inserted under theballoon 182. Accordingly, the camera 16 can take images distally to theballoon182. The camera 16 can be removed from the patient, while thedevice 170 remains in place in the patient. The balloon 182 can beinflated with a means 184.

The second tubal body 180 comprises a lumen 182. The tubal body 180 isattached along the proximal-distal axis of the tubal body 172. Thisadditional tubal body 180 can be used for positioning an esophagealblocker 186 which can be then placed in the patient's esophagus underdirect visualization with the camera 16. The esophageal blocker 186 isequipped with a balloon 188 at the distal end. The balloon 188 can beinflated with a means 190 and seal the patient's upper esophagus. Inaddition, the device 170 is equipped with a second balloon 182 which iscircumferential and wraps around the bodies 172 and 180, and locatedproximally to the balloon 188. The balloon 182 can be used to inflatewith the means 184. The balloon 182 used for sealing the upper pharynx.Thus, the device 170 may act as a supraglottic airway with theendotracheal tube 10 pulled back proximally in the device 170 with theendotracheal tube 12 inflated.

FIG. 10E provides a further embodiment of an oral airway device,generally 190. The device 190 comprises a curved tubal hollow body 192with a distal end 192A and a proximal end 1926. The tubal body 192 endswith a plate 194 at the proximal end 1926. The plate 194 isperpendicular to the tubal body 192. A camera 16 is inserted through anopening 196 in the plate 194. The camera 16 then runs along theproximal-distal axis (192B-192A) of the tubal body 192 such that adistal end 16A of the camera tube 16 can be aligned with the distal end192A of the tubal body 192.

A bougie 198 or any other tool can be inserted into a central lumen 200of the tubal body 192. The distal end 198A of the bougie 198 canprotrude from the lumen 200 distally. The patient's tissues can bemanipulated with the bougie 198 under the continuous visualization bythe camera 16. As the camera 16 can slide along the tubal body 192,images can be taken at different locations with respect to the distalend 192A of the tubal body 192. The camera 16 can be easily removed fromthe patient, while the tubal body 192 remains in place.

In the embodiment of FIG. 10F, the oral airway device 190 of FIG. 10E isassembled with the endotracheal tube 10. In this embodiment, the bougie198 is inserted under the cuff 13 of the endotracheal tube 12. Thisallows for an insertion of the endotracheal tube 10 under the continuedvisualization from the camera 16. The insertion can be guided with thebougie 198. After the insertion has been completed, the bougie 198, thecamera 16 and/or the tubal body 192 can be removed, while theendotracheal tube 12 still remains inserted in the patient as needed.

FIG. 11A depicts a further embodiment of an oral airway device withadjustable length for ventilation, continual visualization, andintubation, generally 200. The device 200 comprises a two-part tubalbody 202 with a lumen 203 and with open proximal and distal ends. Thelength of the two-part tubal body 202 can be adjusted because thetwo-part tubal body 202 is made from an outer cylindrical tube wall 204and an inner cylindrical tube 206, wherein the inner cylindrical tube206 is at least partially inserted into the outer cylindrical tube 204.The inner cylindrical tube 206 can be extended from the outercylindrical tube 204, thus increasing the length of the two-part tubalbody 202, as needed.

The inner cylindrical tube 206 can be also retracted back inside of theouter cylindrical tube 204, thus decreasing the length of the two-parttubal body 202, as needed. The diameter of the outer cylindrical tube204 is larger than the diameter of the inner cylindrical tube 206. Thus,the lumen 203 of the outer cylindrical tube 204 has a diameter largerthan the lumen 207 of the inner cylindrical tube 206.

The inner cylindrical tube 206 is at least partially inserted inside ofthe larger outer cylindrical tube 204. The inner cylindrical tube 206can rotate around inside the outer cylindrical tube 204. The innercylindrical tube 206 can also move distally and it can be extendeddistally from the outer cylindrical tube 204, thus the length of thetubal body 202 can be elongated or shorten, as may be needed. In someembodiments, the cylindrical tube 206 can be completely separated andremoved from the cylindrical tube 204. The tube 204 comprises a plate208 near its proximal end. The plate 208 is perpendicular to thecylindrical tube 204. After the insertion into a patient, the plate 208prevents sliding of the device 200 into the patient's oral cavity.

At least one of or both cylindrical tubes 204 and 206 are curved to fitthe curvature of the patient's tongue and prevent the tongue fromrolling back and abstracting the patient's airways. In alternativeembodiments, the cylindrical tubes 204 and 206 are not curved, but theycan be made of a plastic or some other flexible material which permitsbending the tubal body 202 as may be needed.

The device 200 may comprise a bougie 210 which may be inserted into thelumen 203 such that the distal end 210A of the bougie 210 can protrudefrom the lumen 207. In some embodiments, the lumen 203 is a completelumen fully separated from the central lumen 203. In other embodiments,the lumen 203 is a semi-lumen which opens into the central lumen 203.

The bougie 210 can be inserted and removed from the tubal body 202 atany time even as the tubal body 202 remains inserted in the patient. Infurther embodiment, at least one of the cylindrical tubes 204 or 206 canbe removed from the patient's oral cavity, while the other cylindricaltube remains inserted in the patient. In some embodiments, thecylindrical tube 206 is removed. In other embodiments, the cylindricaltube 204 is removed.

The device 200 comprises a camera 16 which may further comprise a wire18. The camera 16 is inserted inside of the cylindrical tube 204 throughan opening 212 located in proximity to the proximal end of thecylindrical tube 204. The opening 212 is located proximally to the plate208. The distal end 16A of the camera 16 can be aligned with a distalend 206A of the cylindrical tube 206 and in near proximity to the distalend 210A of the bougie 210. Accordingly, the bougie 210 can be operatedunder the continuous visualization from the camera 16.

FIG. 11B depicts an embodiment in which the device 200 is furtherassembled with the endotracheal tube 10 described in embodiment of FIG.1A. It will be appreciated by a person of skill, that any otherendotracheal tube can be also used.

FIGS. 11C and 11D are an enlarged view of a distal portion of the device200 from FIG. 11A. In the embodiment of FIG. 11C, the camera 16 isinserted into a wall of the cylindrical tube 206 and the distal end 16Aof the camera 16 remains at the distal end 206A of the cylindrical tube206. In the embodiment of FIG. 11D, the camera 16 can slide distallyfrom the distal end 206A of the cylindrical tube 206. In thisembodiment, the camera 16 can protrude outside the distal end 206A. Thecamera 16 can be retracted back into the wall of cylindrical tube 206.FIG. 11E provides a further embodiment of the device 200. In thisembodiment, there is no separate opening for the camera 16 on the sideof the cylindrical tube 204. Instead, the camera 16 is integrated in thewall of the cylindrical tube 206.

FIGS. 12A and 12B provide a further embodiment of a device, generally220. The device 220 comprises a camera 16 combined with a stylet 222which provides a backbone and shape to the otherwise flexible camera 16.As can be seen in the embodiment of FIG. 12B, the stylet 222 can becurved. The camera 16 can comprise a wire 18. The camera 16 is furthercombined with a hollow tube 224. Various tools, such as for example abougie 226 can be inserted through the tube 224. Because the tube 224has an open distal end 224A, the bougie 226 can protrude from the tooltube 224 distally to the distal end 16A of the camera 16. Accordingly,the bougie 226 can be manipulated under the continuous visualization ofthe camera 16. The device 220 can be used in combination with any othermedical devices. The device 220 can be used for guiding a placement of amedical device, such for example an endotracheal tube. The placement ofthis medical device can be guided by the bougie 226 which can be used tomove tissues away from the medical device passage under the continuousvisualization from the camera 16. The stylet 22 can be made from amaterial (such as plastic for example) which can be bent into aparticular shape as needed.

FIG. 13 provides a further embodiment for an oral airway device,generally 230. It comprises two hollow tubes. A first hollow tube 232 isinserted inside of a second hollow tube 234. The assembly of the twohollow tubes 232 and 234 is flexible such that the first hollow tube 232can rotate around inside the second hollow tube 234. The second hollowtube 234 can also rotate around the first hollow tube 232.

At least the second hollow tube 234 or both hollow tubes 232 and 234 arecurved such that the oral airway device 230 follows the contour of theroof of a patient's month. After it is inserted into a patient, the oralairway device 230 curves over and rests on top of the patient's tongueand therefore, it prevents the patient's tongue from abstracting thepatient's airway.

The first hollow tube 232 is longer in length than the second hollowtube 234. The first hollow tube 232 can slide along the proximal-distalaxis A-B in and out from the second hollow tube 234. A distal end 232Aof the first hollow tube 232 can extend outside the second hollow tube234 and retract back inside the second hollow tube 234. Thus, the lengthof the device 230 can be increased or decreased, and otherwise can beadjusted as needed. This adjustable size of the oral airway 230 providesa significant technical advantage and can avoid complications such as afailure to hold the tongue in place if an oral airway is too short orunintentionally pressing the tongue back into the airway if an oralairway is too long.

After the placement in the patient is completed, the first hollow tube232 can be removed from the patient, while the second hollow tube 234remains in place. In alternative, the second hollow tube 234 may remainin the patient, while the first hollow tube 232 is removed from thepatient. This allows for easy cleaning and replacement of either of thetwo tubes 232 and 234 if needed.

A camera 16 is attached to the second hollow tube 234 externally in theembodiment of FIG. 13. A distal end 16A of the camera 16 is in nearproximity with the distal end 234A of the second hollow tube 234. Thesecond hollow tube 234 ends with a plate 236. The plate 236 has an ovalshape with no sharp edges. The purpose of the plate 236 is to stayaround the patient's lips while the hollow tubal body 234 is inserted inthe patient. Thus, the plate 236 keeps the device 230 from sliding intothe patient's pharynx after the device 230 has been placed. The plate236 has two openings, 238 and 240.

The opening 238 is positioned in the center of the plate 236 and is usedfor insertion of the first hollow tube 232 into the second hollow tube234. The first hollow tube 232 is inserted into the second hollow tube234 through the opening 238 such that the proximal end 232B is proximalto the plate 236.
